Description

Technical Field

[0001] This utility model relates to the field of steel sheet pile technology, and in particular to a steel sheet pile for bridge ramp construction. Background Technology

[0002] Steel sheet piles are thin-walled steel sections with interlocking edges. Through the interlocking of the interlocking edges, they can form a continuous and sealed retaining structure. They are commonly used in foundation pit support, retaining walls, seepage prevention walls, cofferdams and other projects. They can effectively block soil and water flow and provide a safe working environment for construction.

[0003] Chinese Patent Publication No. CN205591208U discloses a straight sheet pile with a protective plate, comprising a straight sheet pile body, interlocking structures symmetrically provided at both ends of the sheet pile body, a protruding structure with pressure-reducing holes in the middle of the sheet pile body, and an arc-shaped protective plate welded to one side. The length of the arc-shaped protective plate is equal to the length of the sheet pile body, and its diameter is smaller than the width of the sheet pile body. The structure is simple; by providing a protruding structure with pressure-reducing holes in the middle of the sheet pile body and an arc-shaped protective plate on the side, the lateral impact and transverse tension of the sheet pile body can be effectively reduced.

[0004] The steel sheet piles in the above-mentioned technology are made of thin-walled steel and are connected by a single interlocking structure, which can easily cause excessive stress and deformation at the connection point. In addition, the thin-walled steel has a thin lateral cross section, which can cause stress concentration when under stress, resulting in poor structural stability. Therefore, this utility model discloses a steel sheet pile for bridge ramp construction to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a steel sheet pile for bridge ramp construction, in order to solve the problems mentioned in the background art that traditional steel sheet piles are made of thin-walled steel and are connected by a single interlocking structure, which can easily cause excessive stress and deformation at the connection point. In addition, the thin-walled steel has a thin lateral cross section, which can cause stress concentration under stress and poor structural stability.

[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems:

[0007] A sheet pile for bridge ramp construction includes a sheet pile body, with sheet pile wing plates on both sides of the sheet pile body. A sheet pile reinforcing bar connects the adjacent sides of the two sheet pile wing plates to the sheet pile body. A perforated pressure-reducing column, connected to the sheet pile body, is inserted between the sheet pile reinforcing bars. The perforated pressure-reducing column contains pressure-reducing hole units, and multiple locking buckles are fixed on the opposite sides of the two sheet pile wing plates.

[0008] As a further embodiment of this utility model, the end of the latch away from the sheet pile wing plate is provided with a first bend, and the end of the first bend is provided with a second bend.

[0009] As a further embodiment of this utility model, the pressure relief hole unit includes a main pressure relief hole located at the center of the porous pressure relief column. The main pressure relief hole is connected to a first pressure relief hole and a second pressure relief hole. The first pressure relief hole penetrates the main body of the sheet pile, and the second pressure relief hole is offset from the main body of the sheet pile.

[0010] As a further embodiment of this utility model, the two sheet pile wing plates are symmetrically distributed about the central axis of the sheet pile body, and the included angle between the sheet pile wing plates and the sheet pile body is 15°.

[0011] As a further embodiment of this utility model, the steel sheet pile reinforcing bar is composed of a limiting part connected to the main body of the steel sheet pile and an extension part extending from the end of the limiting part to the end of the wing plate of the steel sheet pile, and the extension part is gradually narrowed from the limiting part to the end of the wing plate of the steel sheet pile.

[0012] As a further embodiment of this utility model, the sheet pile body, sheet pile wing plate, sheet pile reinforcing bar, multi-hole pressure relief column and locking buckle are integrally formed.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model discloses a steel sheet pile for bridge ramp construction. The multi-locking design allows adjacent steel sheet piles to be connected through multiple locks. Compared with the traditional single-locking design, there are more connection points and the connection is more secure, which can effectively prevent the steel sheet pile from deforming due to external forces during construction.

[0015] This utility model discloses a steel sheet pile for bridge ramp construction. The presence of reinforcing ribs in the steel sheet pile allows the stress to be distributed more evenly throughout the structure when the steel sheet pile is under load, avoiding stress concentration in a certain part and causing local damage. This stress dispersion mechanism effectively improves the service life and reliability of the steel sheet pile, enabling it to work stably for a long time in complex construction environments.

[0016] This utility model discloses a steel sheet pile for bridge ramp construction. The pressure relief holes evenly distributed along the multi-hole pressure relief column can effectively drain groundwater or water accumulated during construction, reduce the pressure of groundwater on the steel sheet pile, ensure the stability of the steel sheet pile during construction, and prevent the steel sheet pile from deforming or being damaged.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Please see Figure 1-5 This utility model provides a steel sheet pile for bridge ramp construction, including a steel sheet pile body 1, with steel sheet pile wing plates 2 provided on both sides of the steel sheet pile body 1. The two steel sheet pile wing plates 2 are symmetrically distributed about the central axis of the steel sheet pile body 1, and the included angle between the steel sheet pile wing plates 2 and the steel sheet pile body 1 is 15°.

[0027] Specifically, the symmetrical design enables the sheet pile to maintain mechanical balance when under stress. Regardless of the direction of the external force, the sheet pile flanges 2 on both sides can evenly distribute the load, avoiding local deformation or damage caused by uneven stress. The 15° angle allows the sheet pile flanges 2 to better transfer stress to the sheet pile body 1 when under stress, while avoiding excessive stress concentration at the connection.

[0028] Furthermore, a steel sheet pile reinforcing bar 3 is connected between the adjacent sides of the two steel sheet pile wing plates 2 and the steel sheet pile body 1. The steel sheet pile reinforcing bar 3 is composed of a limiting part 31 connected to the steel sheet pile body 1 and an extension part 32 extending from the end of the limiting part 31 to the end of the steel sheet pile wing plate 2. The extension part 32 is gradually narrowed from the limiting part 31 to the end of the steel sheet pile wing plate 2.

[0029] Specifically, the main function of the sheet pile reinforcing bar 3 is to distribute the stress acting on the sheet pile throughout the entire structure, preventing stress concentration at a certain point and causing local damage. This enhances the sheet pile's bending and shear resistance, ensuring its stability during construction and providing reliable safety assurance for the construction. It is worth noting that the sheet pile reinforcing bar 3 is placed at the upper end of the sheet pile, which avoids its influence on the sheet pile installation process and helps reduce driving resistance.

[0030] Furthermore, a porous pressure-reducing column 4, connected to the sheet pile body 1, is provided through the reinforcing bars 3 of the sheet pile. The porous pressure-reducing column 4 is provided with a pressure-reducing hole unit 5. The pressure-reducing hole unit 5 includes a pressure-reducing main hole 51 located at the center of the porous pressure-reducing column 4. The pressure-reducing main hole 51 is connected to a first pressure-reducing hole 52 and a second pressure-reducing hole 53. The first pressure-reducing hole 52 is provided through the sheet pile body 1, and the second pressure-reducing hole 53 is distributed in a staggered manner with the sheet pile body 1.

[0031] Specifically, during construction, the presence of groundwater may exert significant lateral pressure on the sheet piles, leading to deformation or damage. By connecting the main pressure relief hole 51, the first pressure relief hole 52, and the second pressure relief hole 53, water can be quickly discharged, thereby reducing water pressure and ensuring the stability of the sheet piles.

[0032] Furthermore, multiple latches 6 are fixed on the sides of the two sheet pile wing plates 2 that are far apart from each other. The latches 6 are provided with a first bend 61 at the end away from the sheet pile wing plate 2, and a second bend 62 is provided at the end of the first bend 61.

[0033] Specifically, the first bend 61 and the second bend 62 are connected in sequence to form a latch 6 structure similar to a "hook", such as... Figure 1 , Figure 2 As shown, adjacent sheet piles need to be placed upside down during assembly so that the interlocking buckles 6 can be connected to each other.

[0034] Furthermore, the sheet pile body 1, sheet pile wing plate 2, sheet pile reinforcing bar 3, porous pressure reducing column 4 and locking buckle 6 are integrally formed;

[0035] Specifically, the hot rolling process is used to integrally form the steel sheet piles, eliminating the weak points that may occur in the connection between different components due to welding or splicing, and reducing structural damage caused by corrosion or wear at the connection points, thus ensuring the overall strength of the structure. It is worth noting that the thickness of the steel sheet pile body 1 and the steel sheet pile wing plate 2 is about 8-12mm, which can meet the load-bearing capacity and stability requirements in complex construction environments. They are preferably made of low-alloy high-strength steel (such as Q460) or high-strength low-alloy steel (such as Q690).

[0036] Working principle: When using, first, according to the construction requirements and site conditions, disperse and stack steel sheet piles along the support line, then measure and mark the steel sheet pile driving position line with white lime, and use a vibratory hammer or static pressure pile driver to drive the steel sheet piles into the ground to the specified depth. After each section is installed, ensure that the interlocking 6 of the adjacent steel sheet piles are well engaged to prevent loosening during construction.
